摘要

In this paper, the squared eigenfunction and the ghost symmetry of the q-Kadomtsev-Petviashvili hierarchy are defined, and then the related problems are investigated. The spectral representation of the eigenfunction and the adjoint eigenfunction are derived. The definition of the ghost symmetry are generalized and the ghost flows on the tau function are also derived.
